SPRING-TIRE WHEEL.

To all whom t may concern.

Be it known that I, RICHARD M. BATZER,'

v speciiication.

This invention relates to wheels, and is primarily directed to resilientwheels, and the principal object of the invention is to provide anordinary wheel with a supplemental rim, of a greater area than the rimof the wheel, the said rims being sustained in spaced relation throughthe medium of a plurality of resilient elements and the lateral movementof the outer rim with regard to the inner rim being entirely preventedthrough the medium of hinged members extending the entire width of bothof the members.

l/Vitli the above and other objects in view the invention resides in thenovel construction and arrangement of elements hereinafter fullydescribed and claimed.

In the accompanying drawing, Figure l is a side elevation of a wheelconstructed in accordance with my invention. Fig. 2 is a sectional Viewupon the line 2 2 of Fig. 1, and looking in the direction of the arrow.Fig. 3 is a sectional view upon the line 3 3 of Fig. 1.

In the accompanying drawing the numeral 1 designates the wheel proper.lThis wheel 1 may be constructed in the ordinary manner and comprises ahub 2 provided with radiating spokes 3 and a rim 4. The rim 4 may beconstructed of metal or any other desired material and is of asuiiicient width to accomplish the purposes for which it is intended.

The numeral 5 designates a hoop of a greater circumference than the rim4 and securely positioned upon this hoop or outer rim 5 and arranged inpairs are a plurality of resilient elements 6. These springs 6 havetheir end convolutions provided with eX- tending threaded portions 7.The rim 4 is provided with a plurality of spaced threaded openingsarranged in pairs and adapted for the reception of suitable bushings 8.The projecting threaded members 7 of the springs 6 are adapted to beinserted within these bushings and to'extend beyond the inner face ofthe rim 4. The extending portions of the threaded members 7 are adaptedfor Specification of Letters Patent.

Application led June 22, 1999.

the reception of suitable nuts or retaining elements 9, whereby thespring members 6 retain the hoop or rim 5 in proper spaced relation withthe inner rim 4 of the wheel, the nuts being in contact with thebushings, so that when the latter wear by constant working of thesprings therein and also the nuts contacting therewith new bushings maybe substituted therefor. The said bushings will prevent the wearing oftheinner rim at the edges of the openings therein. It is of course to beunderstood that the rim 5 is constructed from rigid material.

It will be noted that by arranging the spring members 6 in pairs oneadjacent the other the liability of the outer rim swinging or moving ina lateral direction away from the inner rim 4 is greatly reduced. Inorder to effectively prevent the lateral movement of the outer rim orhook 5 upon the inner rim 4, I have provided a hinged member 10. Thesemembers 10 are secured to the inner face of the rim 5 and the outer faceof the rim 4 between the spaced resilient elements 6. The members 10each comprise a pair of elements'll and 12 hingedly connected with therim 4 as at 13 and to the -rim 5 as at 14, while the ends of the saidmembers 11 are hingedly connected together as at 15. The hinged orretaining members 10 are of a width equaling the width of the rims 4 andi5 and it will `be noted that by providing the wheel with this structurethe rim 5 is effectively supported upon the rim 4 and lateral movementof the said rim 5 is entirely prevented, while at the same time themember 10 does not at all interfere with the action of the springs orresilient members.

It will be obvious that by reason of the threaded engagement of the nutson the inner ends of the springs 6, the rim 4 may be centered withrespect to the outer hoop or rim by merely adjusting the nuts, also thesaid nuts when adjusted will increase or decrease the tension of thesaid spring to regulate the yielding quality of the wheel.

Having thus fully described the invention what is claimed as new is:

The combination with a wheel having a rim provided with spaced threadedapertures, of a tread rim concentrically disposed with respect to thesaid irst named rim, coiled retractile springs having straight aliningends, each spring being connected at its outer end to the said tread rimto lie flush with the outer face of the said rim and at its oppositeinner end passed through the respect to the tread rim, and means forpre- 10 alining aperture in the Wheel rim, bushings venting relativelateral movement of one detaohably threaded in the apertures and rim tothe other.

surrounding the inner ends of the said l In testimony whereof I affix mysignature y' springs, the said bushings being held ixed in presence oftWo Witnesses.
